Lazinga is for English speakers learning Spanish. It generates fully personalized Spanish podcasts on demand — no two are the same. Unlike static podcast libraries, every conversation is AI-generated to match your exact CEFR level (A1–C2), includes vocabulary you choose, and covers scenarios you pick.

Diffyn's answer:

Addresses workflow and change management on LLM prompts, provide teams with traceability and visualization of tests across multiple models, provide deeper understading into efficiency of these prompts.

Lazinga's answer

Most Spanish learning tools either teach isolated sentences (Duolingo) or offer generic podcasts that aren't tailored to your level (SpanishPod101). Lazinga bridges that gap — it's the only tool that creates custom listening practice with your vocabulary, at your level, for free.

Lazinga's answer

Spanish learners at any level (beginner to advanced) who want immersive listening practice tailored to their needs. This includes self-studiers supplementing apps like Duolingo, travelers preparing for trips to Spanish-speaking countries, intermediate learners hitting a plateau, and students looking for contextual vocabulary reinforcement. The audience skews mobile-first (78% mobile traffic) and is primarily in the US, Canada, UK, Australia, and Latin America.

Diffyn's answer:

Professionals incorporating LLMs or AI tools in their workflow and wants to keep track of changes and test their prompts.

Lazinga's answer

Lazinga was born from a simple frustration: existing Spanish podcasts are either too easy or too hard, and they never cover the specific words you're trying to learn. They also can't prepare you for custom context-based conversations. The idea was to use AI to give every learner what previously only an expensive private tutor could provide — content made just for you. The name "Lazinga" is a playful nod to making language learning feel like a win.

Diffyn's answer:

I started working on Diffyn when I notice that prompting has become an essential part of work across many industries. While there are version control platofrms like github, they are not designed for just prompt management are can be overkill such applications, it is also not integrated natively with various LLMs and relevant tools for users to validate ideas and visualise results properly.

Lazinga's answer

Lazinga is a free consumer tool, so it doesn't have enterprise customers. Its users are individual Spanish learners worldwide — from complete beginners generating their first practice conversation to advanced speakers looking for challenging, natural dialogue on niche topics. Traffic comes primarily from the US, Costa Rica, Canada, the UK, and Australia.
